php5.4版本mcrypt_encryp提升到php7.0 openssl_encrypt,加密字段不一样。

How to encrypt php7.0 openssl_encrypt

今天有个加密,使用的加密字段和key,加密模式都一样,可是加密后的数据不一样,
这是代码片段

<?php
     $privateKey = "qewrvxffbfdhsfdgh";
     $iv    = "234253454354352";
     $data  = "测试用的数据";
     $encrypted = mcrypt_encrypt(MCRYPT_RIJNDAEL_128, $privateKey, $data, MCRYPT_MODE_CBC, $iv);
     echo(base64_encode($encrypted));
     echo "\n";
 >

加密后的数据是gHXA5vo5hEMxjthYNq/gborXWNETPw0rYEb2FspAYzc=

下面是使用php7.0版本以上不支持mcrypt_encryp函数进行加密的代码

<?php
     $privateKey = "qewrvxffbfdhsfdgh";
     $iv    = "234253454354352";
     $data  = "测试用的数据";
     $encrypted=  openssl_encrypt($data,&#39;aes-128-cbc&#39;, $privateKey, OPENSSL_RAW_DATA, $iv);
	 echo(base64_encode($encrypted));
     echo "\n";
 >

加密后是gHXA5vo5hEMxjthYNq/gbtwwm1TlRzsRBI64TrEo3P8=

1.gHXA5vo5hEMxjthYNq/gborXWNETPw0rYEb2FspAYzc=

2.gHXA5vo5hEMxjthYNq/gbtwwm1TlRzsRBI64TrEo3P8=

是不是不一样,这样加密出来的数据不仔细查看,会认为是一样的数据。

要想保证加密一样,将php7.0的代码修改如下

<?php
     $privateKey = "qewrvxffbfdhsfdgh";
     $iv    = "234253454354352";
     $data  = "测试用的数据";
		if (strlen($data) % 16) {
		            $data = str_pad($data,strlen($data) + 16 - strlen($data) % 16, "\0");
		        }
		 $encrypted=  openssl_encrypt($data, &#39;AES-128-CBC&#39;,$privateKey,OPENSSL_NO_PADDING,$iv);
     echo  (base64_encode($encrypted));

加密后的数据是gHXA5vo5hEMxjthYNq/gborXWNETPw0rYEb2FspAYzc=,这样就保持一致了。
